Update Chart Y Axis Markers

[0xModene]

Is your feature request related to a problem? Please describe.
The YAxis component's min/max labels aren't clear, which can be problematic since the numbers are so close to the price.

Describe the solution you'd like
The YAxis should prepend the current values with High and Low, respectively.

Describe alternatives you've considered
If you have a better idea to indicate to the user that these represent the Y Axis range (ie. making the chart itself more distinguishable as well), then go ahead and try that.

I'll play around with it and see what I can come up with for a solution
